Application of Five Stages Electrostatic Precipitation Technology in Renovation of Dust-Collector for Power Station Boiler

Through analyzing the dust characteristics and operating status, combining with electrode matching experiments and simulation condition test, this paper has carried out performance renovation on a three-fields wire-plate type electrostatic precipitator(ESP) for 4
